STRUCT IEEE80211_TX_RATE_CONTROL(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct ieee80211_tx_rate_control — rate control information for/from RC ✨

okay bestie, welcome to the Kernel API Manual entry for struct ieee80211_tx_rate_control 🎀 this is the little bundle of info that gets handed to your rate control algorithm and (sometimes) handed right back, and honestly? it's giving "middleman with main character energy" 🦋

🌸 SYNOPSIS 🌸

struct ieee80211_tx_rate_control {
    struct ieee80211_hw *hw;
    struct ieee80211_supported_band *sband;
    struct ieee80211_bss_conf *bss_conf;
    struct sk_buff *skb;
    struct ieee80211_tx_rate reported_rate;
    bool rts, short_preamble;
    u32 rate_idx_mask;
    u8 *rate_idx_mcs_mask;
    bool bss;
 };

✨ Members ✨

  • hw — the actual hardware that the algorithm is being invoked for 🫶 like, whose radio are we doing math for rn.
  • sband — the band this frame is being transmitted on 📡 so you know which playground we're in.
  • bss_conf — the current BSS configuration 👑 the whole vibe of the network we're sitting in.
  • skb — the skb that will be transmitted, and ngl the control information inside it needs to be filled in ✍️ that's the homework, bestie, don't skip it.
  • reported_rate — the rate control algorithm can fill this in to say which rate should be reported to userspace as the current rate and used for rate calculations in the mesh network 💫 lowkey the whole point of the field.
  • rts — whether RTS will be used for this frame because it is longer than the RTS threshold 📏 (long frame = RTS moment, no cap).
  • short_preamble — whether mac80211 will request short-preamble transmission if the selected rate supports it ⚡ like, only if, okay? conditional queen.
  • rate_idx_mask — user-requested (legacy) rate mask 🎯 old-school but still iconic.
  • rate_idx_mcs_mask — user-requested MCS rate mask, and it's NULL if not in use 🙈 so always vibe-check it before dereferencing, fr fr.
  • bss — whether this frame is sent out in AP or IBSS mode 🏠 iykyk.

and that's the whole page, bestie 💜 you ate that. now go fill in your skb control info before someone notices 🙈
